Review on Inflatable Adapter Multifunction Replacement Accessories by Eddy Borghesi

Durable 4 pack Halkey Roberts inflation valve adapter kit. Halkey-Roberts .74 OD, .525 ID, .935 length with no rings installed. The outside diameter of the opposite end of the hose is 0.8, the length is 0.9. The end of the hose is so thick that it cannot be crushed when inserted into the hose. Comes with 2 soft O-rings. One is .165 thick, the other .23. The rings have a small recessed circle in the center on one side, intended for sealing. See photo. All measurements are in inches.
